Many studies have shown that adding an appropriate amount of black soldier fly larvae or insect meal to chicken feed can significantly improve the growth performance of chickens. For example, adding 5%-10% of black soldier fly larvae to broiler feed can increase the average daily weight gain of broilers by 5%-10% and increase the feed conversion rate by 5%-8%. Adding 3%-5% black soldier fly powder to laying hen feed can increase the egg production rate by 3%-5% and reduce the feed-to-egg ratio by 3%-5%. Black soldier flies are rich in high-quality protein and fat, and have a balanced amino acid composition, making them easy to digest and absorb. Adding black soldier flies to chicken feed can improve the utilization of protein and energy in the feed and reduce feed waste. At the same time, the shell of black soldier fly larvae is rich in chitin, which can promote the growth of beneficial bacteria in the intestinal tract of chickens, improve the intestinal microecological environment, and improve the digestion and absorption rate of feed. Black soldier fly is rich in unsaturated fatty acids, such as linoleic acid, linolenic acid, etc. These fatty acids have an important impact on the meat quality of chicken. Studies have found that adding black soldier flies to chicken feed can increase the content of unsaturated fatty acids in chicken, reduce cholesterol content, improve the taste and flavor of chicken, and improve the quality of chicken. Black soldier flies contain a variety of biologically active substances, such as antimicrobial peptides, lysozyme, etc. These substances can enhance the immunity of chickens and improve their disease resistance. Adding black soldier flies to chicken feed can reduce the morbidity and mortality of chickens, reduce the use of drugs, and ensure the healthy breeding of chickens. As a new feed ingredient, black soldier fly has broad application prospects in chicken breeding. First of all, the black soldier fly can effectively solve the problem of organic waste disposal, realize resource utilization of waste, and reduce environmental pollution. Secondly, the breeding cost of black soldier flies is low and easy to produce on a large scale, which can alleviate the pressure of shortage of feed resources. Finally, the black soldier fly has significant effects in improving chicken growth performance, feed utilization, meat quality and immune function, and can bring higher economic benefits to farmers. In summary, the black soldier fly, as a new insect protein source, has significant application effects in chicken breeding. Adding an appropriate amount of black soldier flies to chicken feed can improve the growth performance, feed utilization, meat quality and immune function of chickens, providing a new way for the healthy breeding and sustainable development of chickens.
